You have confused yourself. The article reference to Russian attack is a separate thing.
RFERL is biased against Russia, so seems to be trying to group them together (apparently it works!).

The claim [about Sadove] by Vladimir Saldo, which could not be independently verified, came after the Ukrainian military said that Russian forces had fired five missiles and dozens of drones over nine regions of Ukraine in an overnight attack. All the missiles and nearly all the drones were shot down, the Ukrainian military said on June 7.

"I'm sure of they were all civies that would've been made clear by that source"
No. Biased anti-Russian source doing it's standard downplay. There are photos available if you look for them. Civilians killed. Sorry.
